On the presence of the genus Ernobius C. G. Thomson, 1859, in Korea (Coleoptera: Ptinidae: Ernobiinae: Ernobiini)

Abstract

Genus Ernobius C. G. Thomson, 1859 is recorded for the first time in Korea, with the presence of two species described from Japan recently collected at the locality of Daejeon. For each species, morphological description, distribution, and biology are given, and pictures of the habitus, antenna, and male aedeagus are provided. The existing problem about the determination of the species because of a poor representation of the aedeagus in the species of the genus given by the different authors is discussed. In addition, the probable specific invalidity of Ernobius sakai Zahradník, 2013 described from China is also discussed.
